Abstract (en)
A Perkins tube type rotary heat exchanger of improved efficiency wherein the Perkins tube evaporation sections (72) are outwardly displaced from the condensation sections (74) by offsetting and/or splaying, to substantially occupy the evaporation sections with Perkins tube working fluid (66) while substantially eliminating the presence of fluid from a major portion of the condensation sections during operation of the heat exchanger. This has the effect of maximizing the internal evaporative area within the evaporation sections and also of maximizing the internal condensing area within the condensation sections of the Perkins tubes (36) thereby materially increasing the energy recovery and effectiveness of the heat exchanger. <IMAGE> <IMAGE>
